Waste asphalt mixture regenerated micro-surfacing and preparation method thereof
The invention belongs to the field of asphalt materials, and particularly relates to a waste asphalt mixture regenerated micro-surfacing and a preparation method thereof, and the preparation method comprises the following steps: S1, collecting waste asphalt from a pavement milling material and a waste asphalt pavement, screening the collected waste asphalt mixture by using a drum screen, and removing large impurities; s2, after preliminary screening, a cyclone separator is used for further fine separation; s3, putting the refined and separated waste asphalt, the modified aggregate, the Portland cement, the admixture and the water into a high-speed shearing machine, uniformly mixing, carrying out shearing development, and carrying out regeneration treatment; and S4, paving the regenerated asphalt mixture on the surface of a road by using a paver and a road roller to form a micro-surfacing. By utilizing the waste asphalt, the lignin, the polystyrene and the calcium carbonate, the raw material cost in the micro-surfacing construction process is reduced, the dependence on traditional petroleum and gravel resources and the influence on the environment are reduced, and the green development concept is met.
本发明属于沥青材料领域，具体地涉及一种废旧沥青混合料再生微表处及制备方法，包括以下步骤：S1、从路面铣刨料和废旧沥青路面中收集废旧沥青，使用滚筒筛对收集的废旧沥青混合料进行筛分，去除大块杂物；S2、经过初步筛分后，使用旋风分离器进一步精细化分离；S3、将精细化分离后的废旧沥青与改性集料、硅酸盐水泥、外掺剂和水投入高速剪切机混合均匀，剪切发育，进行再生处理；S4、将再生处理后的沥青混合料用摊铺机和压路机铺设在道路表面，形成微表处。本发明通过对废旧沥青、木质素、聚苯乙烯和碳酸钙的利用，降低微表处施工过程中的原料成本，减少对传统石油和砂石资源的依赖和对环境的影响，符合绿色发展理念。
